Otherness Watches Us From The Shadows

Every day things happen in the world that cannot be explained by any law of things we know. Every day they're mentioned and forgotten, and the same mystery that brought them takes them away, transforming their secret into oblivion. Such is the law by which things that can't be explained must be forgotten. The visible world goes on as usual in the broad daylight. Otherness watches us from the shadows.
--Fernando Pessoa (from "A Factless Autobiography")
